Overview
iW1760 Off-Line Digital Green-Mode Quasi-Resonant PWM Controller 1.
0 Features ●● No-load power consumption < 50mW at 230VAC along with fast dynamic load response and short turn-on delay in typical 20W and above adapter applications ●● Primary-side feedback eliminates opto-isolators and simplifies design ●● Adaptively controlled soft-start enables fast and smooth start-up for a wide range of capacitive loads (from 330μF to 6,000μF) with output voltage up to 12V ●● Tight constant-voltage regulation across line and load range ●● Proprietary optimized 79kHz maximum PWM switching frequency with quasi-resonant operation achieves best size, efficiency and common mode noise ●● User-configurable 5-level cable drop compensation provides design flexibility ●● EZ-EMI® design enhances manufacturability ●● Adaptive multi-mode PWM/PFM control improves efficiency ●● No external loop compensation components required ●● Built-in single-point fault protections ...
